Abstract

The invention relates to an irinotecan hydrochloride composition, which is a composition by using irinotecan hydrochloride as a main drug and an auxiliary solution consisting of sorbic alcohol, lactic acid, alkaline regulation solution and injection water as dissolving solution. The preparation method comprises the following steps: weighing sorbic alcohol and lactic acid in a container according to the prescription, adding the injection water, stirring to dissolve, and regulating the pH to be between 3.0 and 4.0 with the alkaline regulation solution; adding the irinotecan hydrochloride with the amount of the prescription, dissolving, adding 0.1 percent activated carbon, stirring for 20 minutes, and decarburizing; filtering with a 0.22mu m microporous filter membrane until the mixture is clear; detecting the intermediate substance; filling in a penicillin bottle, plugging a butyl rubber plug, and rolling a cap; and performing leakage inspection and light inspection to the sample after high-pressure sterilization, and packaging after the sample is qualified in quality inspection.
